Dragging any app to the Dock simply creates a link icon for that app in the Dock.

You will be able to position that where you want it, and the original app remains inside that folder. AND, if you want the Stellarium app in your Dock, drag that Stellarium app (inside the folder) to the Dock. Leave that app where it is, as it might need to be in that location to work correctly.
If you OPEN that folder, you will likely find the real app. So, it's likely that icon represents a folder, and the end of Dock is the correct place for that. It might already be in the Applications folder.īy the way, the right end of the Dock (near where the trash is located) is NOT for applications, but is for folders. If it is an alias, you could leave it where it is, as it is just a link to the app.Īlso, if it is an alias, you can again right-click the file, choose "Show Original", and that will then show you where the linked file or app is actually located. You can also right-click on the file, choose Get Info, and that information window will show you what type of file it is.

An alias file will have a small arrow on the bottom left corner of the file's icon.
